Art Deco Earrings Colour Change Sapphires
ByArt Deco Earrings Colour Change Sapphires
I’ve spent a lot of time investigating these art deco vintage earrings today, they are so beautiful and rare I though I would show them to you.
At first glance , I though I had a nice but unremarkable pair of art deco amethyst set earrings. Then when I put them under artificial light I saw they were a stunning magenta colour which is certainly not something you would expect from amethysts. Out comes the gem testing machine and to my surprise they test as sapphires.
These colour change sapphires measures about 1 cm diameter and vary between a blue purple colour and a red magenta – sometimes you see both colours at once. These gems are very very clear and so I suspect that they have been treated in some way to create the colour or are possibly lab grown. I know that these techniques and treatments were available in the 1920s when these earrings would have been made.
Any one knowing more about this type of stone , please do get in touch and let me know more.

Hello
Is it possible that they are tanzanite rather than sapphire? (tanzanite is trichoric) – i’m not sure how the test you use works, so apologies if it is not possible to mix these two up.
They are gorgeous, and I’m sorry they’re a little beyond my price range.
I’m commenting as well because I wanted to ask you if there was a ‘recently added’ section to your website? I often look at it (longingly) but it would be really helpful if there was a specific area to see what had been added since I last looked. If there is one and i’ve just missed it, apologies.
Thanks very much, and your website is great.

Hi Abi,
Thanks for your interest. I am always prepared to consider I am wrong when judging gemstones as it is a real minefield. In this case I have tested the stones with an electronic Gem Tester which clearly differentiates between Tanzanite and Sapphires ( opposite ends of the read out and no overlap).
Great minds think alike and I am having a freshly added section to my shop when the new design goes live in a couple of weeks time. I add 30 to 40 items a week and so I expect that items will stay in that section for a week at the most.
Your kind comments are appreciated
Anne
